Methods, systems and computer-readable media for tracking a position of an object

ABSTRACT

Embodiments provide a method and system for tracking a position of an object. The method may include creating a plurality of geofences on a map of a predefined location and identifying, by Wi-Fi trilateration, the position of the object within the created geofence. Further, a floor layout of the predefined location may be created by a handheld device. The position of the object can be represented on the created floor layout.

FIELD

The field relates generally to a method and system for location tracking. More specifically, the field relates to a method and system for tracking a location of an object by Wi-Fi trilateration.

BACKGROUND

Tracking a position of an object in a predefined location lacks the required accuracy while employing existing technologies. For instance, global positioning system (GPS) technology fails in determining the position of the object inside a solid structure such as a building, with an accuracy of three to five meters. Additionally, current location tracking technologies merely provide a set of location co-ordinates of the object. The set of location co-ordinates may lack sufficient information in representing the position of an object in terms of proximity of the object to a pre-designated location within the predefined location.

Further, for the purpose of servicing location-based services in a predefined location, existing tools require a user to draw a floor layout of the predefined location with a set of drawing tools. Such an approach is a cumbersome process and tends to be faulty in the event the user fails to represent a pre-designated location on the floor layout. There is a need for a method and a system that can automatically draw the floor layout on a handheld device, as the user traverses the predefined location.

Hence, there is a need for a method and a system that can track the position of the object in a predefined location with an accuracy level of two to five meters. The alternate method and system must enable representing the position of the object on the floor layout of the predefined location, in terms of proximity of the object to a pre designated location of the predefined location. Thus a method and a system for tracking the position of the object on the floor layout are proposed.

SUMMARY

The present invention provides a method for tracking a position of an object. In accordance with a disclosed embodiment, the method may include creating a plurality of geofences on a map of a predefined location and identifying, by Wi-Fi trilateration, the position of the object within the created geofence. Further a floor layout of the predefined location may be created by a handheld device and the position of the object can be represented on the created floor layout.

In an additional embodiment, a system tracking a position of an object is disclosed. The system comprises a drawing pad configured to create a plurality of geofences on a map of a predefined location. The system further includes a tracking module configured to identify a position of the object, by Wi-Fi trilateration, within the created geofence. Further, a floor map generator shall be configured to create a floor layout of the predefined location; and a display module can be configured to represent the position of the object on the created floor layout.

These and other features, aspects, and advantages of the present invention will be better understood with reference to the following description and claims.

DETAILED DESCRIPTION

Disclosed embodiments provide computer-implemented methods, systems, and computer-program products for tracking a position of an object in a predefined location. The predefined location maybe an indoor location or an outdoor location. Further, automatic creation of a customized floor layout of the predefined location depicting a plurality of elements within the predefined location can improve the tracking experience in location determining systems. The disclosed methods and systems provide techniques for creation of such customized floor layouts and thereby representing the position of the object on the customized floor layouts.

FIG. 1 illustrates an embodiment of a method of practicing the present invention. At step 102, a plurality of geo-fences may be created on a map of the predefined location. The map maybe a digitized visual layout of the predefined location accessible from a computer enabled device. A user involved in creation of the geofences may draw the geofence on the digitized visual layout via an input interface module. The created geo-fences may be in the shape of a circle, line or a polygon. Further, a point of interest may be associated with each created geo-fence. At step 104, a position of the object within the created geo-fence can be identified by Wi-Fi trilateration method. At step 106, a floor layout of the predefined location can be created using a handheld device, where a plurality of positions of the predefined location is fetched by the handheld device. The plurality of positions of the predefined location maybe tagged as per the functionality of each position, by the user via the input interface module. The position of the object maybe represented on the created floor layout at step 108.

FIG. 2 illustrates an alternate embodiment of a method of practicing the present invention. At step 202, a plurality of geofences can be created on a map of a predefined location. Further, at step 204, a set of location co-ordinates of the created geo-fence maybe retrieved by an interface module, and stored in a repository subsequently at step 206. A user involved in creation of the geofences may draw the geofence on the digitized visual layout via an input interface module. The created geo-fences may be in the shape of a circle, a line or a polygon. Further, a point of interest may be associated with each created geo-fence. Further, at step 208, the position of the object maybe identified by a method of Wi-Fi trilateration, within the created geofence. The method of Wi-Fi trilateration includes selecting the position of the object as a best location from a plurality of locations, whereby the plurality of locations is determined by a plurality of mathematical models. The plurality of mathematical models may include a polygon centroid method, a polygon triangle centroid method, and an expanding circles method. As the object traverses within the predefined location, knowledge of the position of the object may be tracked via preset triggers associated with the created geofences. For instance, a trigger maybe associated with a geofence such as a conference room of a predefined location such as an office building. The associated trigger can be of raising an alarm, when the object crosses a boundary of the conference room. Thus the user may be notified, of the exit of the object from the given conference room. Further, triggers can involve any other action such as transferring data downstream to an application. Hence at step 210, an action can be triggered when the object crosses the boundary of the created geofence.

Step 212, involves creation of a floor layout in a detailed manner, of the predefined location. A set of location co-ordinates of a plurality of positions of the predefined location can be collected via a handheld device, as the handheld device is made of traverse throughout the predefined locations. A location co-ordinate of a position usually includes a latitude, a longitude and an altitude of the position. At step 214, the user of the handheld device, may tag each position based on a functional aspect of the position. For instance, a location co-ordinate of the conference room on a first floor of the building maybe tagged as “first floor conference room”. The set of location co-ordinates and a tag information of the plurality of positions of the predefined location may be sent to a server, and stored in the repository. At step 216, the stored set of location co-ordinates and the tag information maybe be utilized for generating the floor layout. Further the position of the object maybe represented on the created floor layout at step 218. The representation of the position of the object on the created floor layout may include, depicting proximity of the object to a tagged position of the generated floor layout. For instance, if the object is located at a location co-ordinate, as identified by the Wi-Fi trilateration method, of (10,20,30) which is at a proximity distance from the conference room whose location co-ordinate is (12, 22, 32), then the representation of the position of the object can be as; the object is location a proximity of the conference room. Such a representation shall aid the user in locating the object more effectively.

Additionally, the position of the object as identified may be stored in the repository on a periodic basis, such that the movement of the object maybe tracked. From the repository, a last point of interest of the object maybe retrieved and based on a past history of the object, a next point of interest the object may traverse to can be suggested.

FIG. 3a illustrates an exemplary system 300 in which various embodiments of the invention can be practiced. The exemplary system 300 includes a server 332, and a handheld device 302 which can be in wireless communication with the server 332. The server 332, includes a drawing pad 308, an interface module 310, a repository 312, a triggering module 313, a receiving module 333, a floor map generator 318, a floor map renderer 316, a transmitting module 320, and a display module 314. The handheld device 302, includes an input module 336, geo-point tagging module 306, a transmit module 330, a receiver 334, a display 338, a computing module 322, and tracking module 326. The tracking module 326 shall include a set of Wi-Fi routers 324, spanning a predefined location.

In the server 332, the drawing pad 308, can be a layer on which a plurality of geofences may be drawn by a user on a digitized visual layout of a predefined location. The interface module 310, shall retrieve the location co-ordinates of the drawn geofences, so as to store the created geofences along with the location co-ordinates in the repository 312. The tracking module 326, shall identify a position of an object 328, where the object 328 maybe located within one of the created geofence, by a Wi-Fi trilateration method. By the disclosed Wi-Fi trilateration method, the position of the object 328, can be determined up to an accuracy of three meters from the actual position of the object 328, when the predefined location is an indoor environment. In another embodiment, a similar accuracy may be achieved when the predefined location is in an outdoor environment. The object 328 can be assumed to be associated with a electronic device capable of wireless communication with the set of Wi-Fi routers 324. The Wi-Fi trilateration includes selecting the position of the object as a best location from a plurality of locations, where the plurality of locations can be determined by a plurality of mathematical models, such as a polygon centroid method, a polygon triangle centroid method, and an expanding circles method. In each of the aforementioned method a distance of the object 328 from set of three Wi-Fi routers are essential in determining the position of the object. The set of three Wi-Fi routers are usually a subset of the set of Wi-Fi routers 324, such that the set of three Wi-Fi routers are closest to the object 328 at a given instant of time. The object 328 shall usually transmit a signal strength as received from each of the set of three Wi-Fi routers periodically to the tracking module 326. Based on the signal strength and techniques well known in prior art, the tracking module 326, can compute a distance r1, r2 and r3 of the object 328 from the Wi-Fi router 1, Wi-Fi router 2 and Wi-Fi router 3 respectively (ref FIG. 4). Further, a set of location co-ordinates C1, C2 and C3 of the Wi-Fi router 1, Wi-Fi router 2 and Wi-Fi router 3 respectively can be retrieved from the repository 312, into the computing module 322. The computing engine 322, shall utilize r1,r2, r3, C1,C2 and C3 in each of the three mathematical models as mentioned above, to determine a set of three location co-ordinates of the object 328. A best of the three location co-ordinates can be determined to be the position of the object 328, by the computing module 322.

In the polygon centroid method as shown in FIG. 4, a distance of the object 328, from a set of three Wi-Fi routers, Wi-Fi router 1, Wi-Fi router 2, Wi-Fi router 3, each situated at center C1, C2, and C3 respectively, can be determined by the tracking module 326, based on a signal strength of the set of three Wi-Fi routers, as received by the electronic device associated with the object 328. The object 328 shall transmit the signal strength as received from the set of three Wi-Fi routers periodically to the tracking module 326. Based on the signal strength and techniques well known in prior art, the tracking module 326, can compute a distance r1, r2 and r3 of the object 328 from the Wi-Fi router 1, Wi-Fi router 2 and Wi-Fi router 3 respectively. A location co-ordinate of the Wi-Fi router 1, denoted as C1 in FIG. 4, can be retrieved from the repository 312, by the computing engine 322. Similarly location co-ordinate C2, and C3, of Wi-Fi router 2 and Wi-Fi router 3 respectively may be retrieved by the computing engine 322. The computing module 322 shall be configured to determine the position of the object 328, by drawing three circles with centers C1, C2, and C3 and radii r1, r2 and r3 respectively. Each of the centers C1, C2 and C3 are joined by line segments C1C2, C2C3, and C3C1 respectively such that line segment C1C2 intersects circle C1 at point P1, and C2 at point P2. Similarly line segment C2C3 intersects circle C2 at point P3 and circle C3 at point P4, and line segment C3C1 intersects circle C3 at point P5 and circle C1 at point P6. Points P1, P2, P3, P4, P5, and P6 are joined to form a hexagon P1P2P3P4P5P6. A centroid Ctl, of the hexagon P1P2P3P4P5P6, can be considered to be a first location of the object 328.

As per the polygon triangle centroid method as illustrated in FIG. 5, the computing engine 322, shall follow similar steps as in the polygon centroid method to form the hexagon P1P2P3P4P5P6. Further point P1 and point P3 are joined to form a triangle P1P2P3. A centroid of the triangle P1P2P3 can be referred as H1. Similarly, point P2 and point P4 can be joined to form a triangle P2P3P4, and a centroid of the triangle P2P3P4 can be illustrated as H2. Point P3 and point P5 are joined to form a triangle P3P4P5, whose centroid can be illustrated as H3. Point P4 and P6 are joined to form a triangle P4P5P6, whose centroid can be illustrated as H4, and point P5 and P1 are joined to form a triangle P5P6P1, and a centroid of the triangle P5P6P1 can be illustrated as H6. Points H1, H2, H3, H4, H5, and H6 can be joined to form an inner hexagon H1H2H3H4H5H6, and a centroid Ct2 of the inner hexagon, shall be determined as a second location of the object 328.

According to the expanding circles method, as illustrated in FIGS. 6a and 6b , the computing engine 322, shall form a triangle C1C2C3 by joining the centers C1, C2 and C3, where C1, C2 and C3 are location co-ordinates of Wi-Fi router 1, Wi-Fi router 2 and Wi-Fi router 3 respectively. Further, using radii r1, r2 and r3, and centers as C1, C2 and C3, respectively, three circles maybe drawn, where the radii r1,r2 and r3 are tracked by the tracking module, as a distance of the object 328, from the Wi-Fi router 1, the Wi-Fi router 2 and the Wi-Fi router 3 respectively. As shown in FIG. 6a , line segment C1C2 intersects circle C1 at point P1 and circle C2 at point P2, line segment C2C3 intersects circle C2 at point P3 and circle C3 at point P4, and line segment C3C1 intersects circle C3 at point P5 and circle C1 at point P6. Points P1, and P2 are joined, points P3 and P4 are joined and points P5 and P6 are joined. A longest line segment amongst P1P2, P3P4 and P5P6 shall be determined as a distance d2. A distance d2/2 shall be added to the radii r1, r2 and r3 to redraw circles with center C1, C2 and C3 are illustrated in FIG. 6b . C1 and C2 can be joined to intersect the circle C1 at A3 and the circle C2 and A2. Further, C2 and C3 can be joined such that line segment C2C3 intersects circle C2 at point A5 and circle C3 at point A4, and C3 and C1 are joined, such that line segment C3C1 intersects circle C3 and circle C1 at point A1. Points A1, A2, A3, A4, and A5 can be joined to form a pentagon A1A2A3A4A5. A centroid of the pentagon A1A2A3A4A5 shall be determined to be the third location of the object 328. The position of the object 328, is determined as a best location from the first location Ct1, the second location Ct2 and the third location Ct3. The best location maybe determined by considering a minimum of a sum of distances of each of Ct1, Ct2 and Ct3 from each of the routers.

In order to represent the position of the object 328, in a meaningful manner to a user, creation of a floor layout of the predefined location is needed. The floor map generator 318, shall create the floor layout of the predefined location, based on an input received from the geo-point collector 304, and the geo-point tagging module 306, of the handheld device 302. As the handheld device 302, traverses along the predefined location, the geo-point collector 304, shall collect a set of location co-ordinates of a plurality of locations traversed by the handheld device 302. For each location, the geo-point tagging module 306, shall place a tag on the location, based on an input received from the user, through the input module 336. The input module 336, can be an input interface, or device, such as a touch screen, a keypad, and the like. The set of location co-ordinates and tagging information of each of the location shall be transmitted by a wireless communication link from the transmitter 330, to the server 332. The receiving module 333, at the server 332, shall receive the set of location co-ordinates and the tagging information, and store the set of location co-ordinates and the tagging information in the repository 312. The floor map renderer 316, shall access the set of location co-ordinates and the tagging information, also referred to as a metadata of the floor layout, and converts the metadata into a visual format of the floor layout. The visual format shall be stored in the repository 312, for further referencing purpose. The visual format shall be displayed on the display module of the 314, of the server, so that the user may visualize the floor layout of the predefined location. Further, the visual layout may be transmitted by the transmitting module 320, to the handheld device 302. The receiver 334, on the handheld device 302, shall receive the visual format of the floor layout and display the visual format on the display 338. Further the display module 314 can represent the position of the object 328, on the created floor layout by disclosing proximity of the object 328, to a tagged position of the created floor layout.

In an alternate embodiment of the system, as shown in FIG. 3b , a tracking module 326, and a computing module 322, shall reside on a server 332. The alternate embodiment shall be useful in situation where a computing capacity of a handheld device 302, is low. Creation of a floor layout of a predefined location where an object 328, needs to be tracked and a determination of a position of the object 328, shall be processed on the server 332. The created floor layout and the tracked position of the object shall be communicated wirelessly to the handheld device 302.
